How +Spell Damage Is Calculated For Mages

[impulse102]

Notes:

# "+X Damage" and "+X Damage and healing" gives the same bonus to damage.
# "up to +X Damage" works the same as +X Damage. ( up to +1-X Damage items dont exist anymore). *1
# the rank of the spell. rank 1 frostbolt do not recieve nearly as much bonus as rank 10. the highest rank of spells gets full bonus.
# how the spell is designed (see further down for explanation).


*1) +X Spell Damage appears on items that have random enchantments (like Green Lens of Frost Wrath), and Up to +X Damage appears on items that always give that (like Shivery Handwraps).

--------------------------------------

Here is a full +spelldamage calculation multiplyer on every mage spell ingame. explanation will follow:

Frostbolt: 0.814
Blizzard: 0.333
Cone of Cold: 0.136
Frost Nova: 0.136

Pyroblast: 1 Hit / 0.714 DoT
Fireball: 1
Fireblast: 0.429
Scorch: 0.429
Flamestrike: 0.285
Blastwave: 0.136

Arcane Missiles: 1
Arcane Explosion: 0.143


--------------------------------------

About + Damage:

Taken from MPS A spells benefits from +Damage, depending on 3 factors (assuming its the highest rank of the spell):
1: cast time
2: number of targets its designed for
3: additional effects
4: the level you first get the spell

what this actually means, is that a spell recieves damage depending on how long the casttime is, wether its an aoe or singletarget spell, if it has any snares/slowing effects, and finally the level.

1: the casttime modifyer for every spell ingame is calculated from a 3.5sec cast base, and can NOT be higher than 1 (i.e pyroblast does not recieve ~ twice the bonus from being a 6sec cast) and can NOT be lower than 0.428 (fireblast and scorch both recieves this same cast time penalty from spelldamage, even though scorch is 1,5sec cast and fireblast is instant).

2: if the spell is an aoe, it recieves 0.333 of the spelldamage as an additional multiplyer.

3: the additional effects modifys the spelldamage recieved by how much of the spell that is intended as damage, and how much is intended as the effect it adds (snare/root/stun). if the spell has a snare effect, it has an additional 0.950 modifyer.

4: the rank of the spell, or actually wich lvl you got the spell. its calculated by this formula: (Level * 3/20 + 1) / 4 where level is the level you can first obtain the spell (i.e. 1 for rank 1 fireball, 6 for rank 2 etc.) remember that casttime might differ on lower lvl spells, wich must ofcourse be taken in consideration! A guiding number is: rank 1 fireball with +200 fire damage gains a mere 24.6 bonus damage.

theese modifyers are all applied unspecced.
i.e it doesnt differ if you use Presence of Mind, if you specc permafrost, impact etc. but the standard spell, and what it is designed for.


--------------------------------------

Example - Cone of Cold (Rank 5):

(casttime) its instant cast, but since 1.5 is the lowest casttime modifier allowed, CoC recieves (1.5/3.5) = 0.428 of total spelldamage by casttime.

(aoe/singletarget) Cone of Cold is an aoe spell, and therefore recieves another multiplyer of 0.333, wich results in a 0.143 bonus from +damage.

(effects) last of all, it also has a snare effect, wich adds a final multiplyer of 0.95, thus making it end up with a 0.136 modifyer.

(level) applying Danyas formula, CoC (Rank 5) is obtained on lvl 56, thus no level formula needs to be calced. it gains full bonus from level.

in total, the calculation for CoC would look like this: (1.5/3.5) x0.333 x0.950 x1 = 0.1355 ~ 0.136.


--------------------------------------

Last of all, a spell descriptions to all spells and why the spelldamage modifyer is/isnt simply just cast time (x/3.5):

Frostbolt: adds a slowing effect.
Blizzard: area of effect (aoe that requires chanelling).
Cone of Cold: area of effect, adds a slowing effect.
Frost Nova: adds a snare effect.
Pyroblast: no modifyer. (recieves 100% of +Damage on hit, and 74% on DoT).
Fireball: no modifyer.
Fireblast: no modifyer.
Scorch: no modifyer.
Flamestrike: area of effect.
Blastwave: area of effect, adds a slowing effect.
Arcane Missiles: no modifyer. singletarget, no effect.
Arcane Explosion: area of effect.

Additional Info:

Talents with +% Damage (Firepower, Piercing Ice, Arcane Instability, Arcane Power) is multiplyed ->after<- +Damage in the formula, so the effect will naturally scale with you collecting +Damage eq.

All the new AQ spell Ranks follow the same above calculations if anyone was curious. tested and reported.

**** dude

complicated..

why can't it just be whatever it says (Fireball Rank 11 is 561 - 715) an when you add allll your +spell damage buffs and gear, lets say its +250.. it would go from (Fireball Rank 11 is 561 - 715) to, when you add the +250, (Fireball Rank 11 is 811 - 965)?

Simple, it would be overpowered. Can you imagine instant spells like holy nova or arcane explosion that would work like that?
